Description

Technical Field

[0001] This invention relates to a template for an SA-grade crash barrier with flower grooves. Background Technology

[0002] In traditional highway bridge concrete crash barrier construction, tie rods are used to fix the inner and outer formwork to resist the lateral pressure of the concrete. Installation requires sleeves and tie rods, and tightening nuts, and the tie rod connections pose certain safety hazards. Furthermore, after the tie rods are removed, the remaining holes need to be sealed again, which can easily lead to quality problems such as grout leakage, root rot, water seepage, and steel corrosion. Secondary repairs also affect the overall appearance of the crash barrier.

[0003] The SA-grade concrete crash barrier with flower troughs has a Ч-shaped cross-section, and the flower troughs should be cast in place along with the crash barrier body. When using traditional tie-bar type guardrail formwork, the presence of the flower trough chamber increases the cross-sectional dimensions of the guardrail, the self-weight of the formwork, and the length and number of tie bars, leading to increased construction safety risks. Higher requirements are placed on the stability of the formwork installation during construction. Additionally, more pre-drilled holes are needed, and auxiliary measures such as grout sealing and reinforcement are required, making the process cumbersome and time-consuming. Summary of the Invention

Then, concrete pouring begins. After the concrete strength reaches the demolding strength, the end molds, outer molds, inner molds, and inner molds are removed in sequence. When removing the inner mold unit 3, first loosen the two adjusting nuts 38 of the inner mold anti-float mechanism 3A, then rotate the screw 37. The I-shaped anti-float steel plate 36 rotates together with the screw 37. When the I-shaped anti-float steel plate 36 is parallel to the two side panels of the inner mold steel panel 30, the I-shaped anti-float steel plate 36 can be removed from the inner mold unit 3, and then the inner mold unit 3 can be removed.
